The number pi is known in mathematics as the ratio of the circumference of the circle to its diameter. Every year, 14 March is celebrated as Pi Day. The reason for this is that in the American date format this day passes as 3/14 and this is reminiscent of pi.

Google employee Emma Haruka Iwao, who lives in Japan, calculated 31 trillion digits of the Pi number with the help of the company's cloud computing service. It was stated that Iwao completed the calculation that needs 170 terabytes of data in 121 days with 25 virtual machines. Stating that he was very impressed by the Pi number since his childhood, Iwao said, "I am very confused. I am still trying to get used to this fact. It was really difficult to break the world record," he said. Iwao said he wanted to improve his record, stating that there is no end in the Pi number.

It was also noted that it would take 332,064 years to put the 31 trillion digits of Pi into the word. The number had previously been calculated with a maximum of 22 trillion digits.

The date of the number Pi dates back to Christ. The symbol Pi is the 16th letter of the Greek alphabet. For the first time, a famous physicist at the Exploratorium in San Francisco in 1998 by Larry SHAW celebrated Pi Day was first celebrated in 2007 in Turkey.
So why is this Pi number so important?
In response, thanks to this ratio, we can calculate areas very easily.
